A server in a remote data center is no longer responsive. Which of the following is the BEST solution to investigate this failure?
The correct answer is C. Out-of-band management. For an unresponsive server in a remote data center, out-of-band management provides access to the server's hardware console and power controls independently of the operating system and network.

Why each option
For an unresponsive server in a remote data center, out-of-band management provides access to the server's hardware console and power controls independently of the operating system and network.
Remote Desktop relies on the operating system and network stack being functional, which is unlikely if the server is unresponsive.
Access via a crash cart requires physical presence at the data center, which is impractical for a server located in a remote data center in another country.
Out-of-band management technologies, such as IPMI, iLO, or iDRAC, offer a dedicated network interface and hardware-level access to a server. This allows administrators to troubleshoot, power cycle, or access the console even when the main operating system or network connection is unresponsive, making it the best solution for remote failures.
A Secure Shell (SSH) connection also depends on the operating system and network services being functional enough to respond to network requests, which is unlikely for an unresponsive server.
